SPECIFICATION forming part of Letters Patent No. 776,055, dated November 29, 1904.

Application filed August 1, 1904.

1'0 all whom/it mag concern:

Be it known that we, VVALLACE D. Gnos- JEAN and WILLIAM G. EHRMANTRAUT, both of Oneida, in the county of Madison and State of New York, have invented certain new and useful Improvements in Oushion-Tufting Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form part of this specification.

The object of our invention is to provide a machine for conveniently and expeditiously tufting cushions, and particularly such cushions as are used in connection with so-called Morris chairs.

In the drawings, Figure 1 shows a vertical section of a machine embodying the features of our invention. Fig. 2 shows a horizontal section taken on line A B of Fig. 1, also showing the parts below the section-line. Fig. 3 shows a section taken on lines C D of Fig. 2 with the parts to the left ofthe section-line. Fig. 4shows, partially in section, the arrangement of buttons and links for producing the tufting and such as is employed in co'n'nection with our machine. Fig. 5 shows another view of the same buttons and links. Fig. 6 shows, in enlarged detail, portions ofthe device and the manner in which the machine operates. Fig. 7 shows in a similar manner-the operation at another stage. Fig. 8'shows an enlarged detail of a portion of a cushion after being operated upon by the machine.

The frame of the machine consists mainly of four corner-bars 1 1 and2 2, which'we prefer to arrange in a horizontal position andsupport upon suitable legs at a convenient height for convenient operation. Supported substantially in the middle of the machine, between frame-bars 1 1 and 2 2, there is a casing 3 of the proper form and size to receive the cushion to be operated upon. At

SerialNo. 219,027. (No model.)

one side the casing3 is provided with a compre'ssion-plate 4, having funnel -shaped projections 4. These funnel-shaped projections 4 are preferably hollow, as shown, and particularly provided with the opening 5, which is of suitable size and arranged to allow the passage of the tufting-buttons used, as will hereinafter appear. The second compressionplate 6 is also provided with similar funnelshaped projections 6, coinciding in position with projections 4 of the plate 4. These funnel-shaped projections 6 are also provided with openings 7 similar to 6,before mentioned. The compression-plate 6 is provided with a frame 8, which gives strength to the plate and serves for other purposes, as will hereinafter appear. A follower 9 is provided, which is of a form and size to receive the frame 8 and is also provided with projections 9, which are adapted to be received in the hollow side of the funnel-shaped projections '6 and preferably quite closely fit the same. The follower 9 is supported byaslide-frame 10, which has bearings on the frame-bars 11 and 22, and the follower moves backward and forward by means of the rack-bar 11, attached to the backand the gear-pinion 12. The pinion 12 is mounted on a shaft 13, supported in suitable hearings in the frame, and the shaft and gear 12 are manipulated by means of a hand-wheel 14, although any other suitable means, including means for the application of power, may be provided in lieu of the handwheel-14. The frame 8, with the compression-plate 6, may besecured on the follower 9 by suitable catches, as 15, provided for that purpose. In the frame at the opposite side of the casing orcom pression-chamber 3 fromthe follower 9 there is provided a reciprocating head 18, provided with a rack-bar 19, which engages with the geafipinion 20. The head 18 finds hearings on the frame-bars 1 and 2 and is operated by means of the handwheel 21 on the shaft 22, which'has bearings in the frame and on which the gear-wheel 20 is secured. The head 18 is provided with a movable plate is supported in its needles register with compression-plate which is preferably a spring and a hook 128, provided on the plate 25', and'adapted to engage with and slide along the bar27. On

the walls or casing her 3 thereare provided a number of springcatches 30, adapted to engage 8 of the movable compression-plate and secure it in position in the compression-chamber.

- For disengaging the catches 30 thereare provided on each side of the machine vertical slides31 and 32, having inclined faces adapted to engagewith the catches 30, respectively, and force them into openpositions. erating' these slides 31 and 32 there may be provided a treadle extension of the slides 31 and 32 may be respectively connected.

The follower 9 is again brought up by means of its operating mechanism, and the projection 9 engages with the button on the link and forcesrit well into position in the pad and in the opening 7 through the funnelshaped projection of the compression-plate. The parts in this position are shown in Fig. 7. The operator now places on the other button, placing it in the somewhat open hook of the link X. catches 30 are released and the catches 15 engaged with the follower 9 and the follower carrying with it the compression plate 6. When the follower, with the compression-plate 6, is removed, the cushion can be removed from the compression-chamber, the buttons which have been attached on -When 'this'has been done, the r side of "the compression plate 4 passing -21- 2 through the openings 5. Of course it will be understood that the cushion is compressed somewhat more tightly than is desired for its final position; but after it is relieved from the pressure of the machine its elasticity will take up the extra length of the link X, which is provided to allow it to project sufliciently to attach the last button, as desired.

oved from the machine, the arrangement A, e bu tons, link, andcushion will be subtantially as shown in Fig. 8. The needleplate 25 is raised to its elevated position and secured on the bar 27 by the hook 28, when the apparatus is ready for a repetition of the operations before described.

What we claim as new, and desire to secure by Letters Patent, is-

1. The combination in a compression-plates having funnel-shaped projections on the opposing surfaces, with means for moving same toward and from each other, substantially as set forth.

When

tufting-machine of 2. The combination in a tufting-machine of compression-plates having coinciding funnelshaped projections on the opposing surfaces, with openings through the points of the projections, substantially as set forth.

3. The combination in a tufting-machine of compression-plates having coinciding funnelshaped projections on their opposing faces, with openings suitable to afford a passage for the tufting-buttons in the [points of the projections, means for moving the plates toward and from each other, needles arranged to be passed through the openings in the projections and means for operating the needles, substantially as set forth.

4. The combination in a tufting-machine of the character described,- the combinationofa compression-chamber having one side formed by a com pression-plate with funnel-shaped in wardly-extending projections, a movable compression-plate having corresponding funnelshaped projections adapted to be operated into the compression-chamber,

and means for operatting the movable compression-plate, 5t follower having projections entering the hollow funnel projections of the compression-plate, needles arranged to be passed through the compression-chamber and through the funnelshaped projections, and means for operating the needles, substantially as set forth.
